Spark Plug Mountain is a 6,320-foot (1,926-metre) mountain summit located above the western shore of Glacier Lake, in eastern King County of Washington state.[5] It's part of the Wenatchee Mountains, which are a subset of the Cascade Range, and is situated in the Alpine Lakes Wilderness, on land managed by Mount Baker-Snoqualmie National Forest.[1] The nearest higher neighbor is Surprise Mountain, 1.0 mi (1.6 km) to the southeast, and Thunder Mountain is set above the eastern shore of Glacier Lake.[1] The Pacific Crest Trail skirts this lake as it passes between Spark Plug and Thunder. Spark Plug Lake, elevation 5,587-ft, lies immediately below the north aspect of the mountain, and Little Spark Plug is the 6,016-ft peak on the north side of this lake. Precipitation runoff from the mountain drains into Surprise Creek and Deception Creek, both tributaries of the Skykomish River.
